bookImplementing Generic Methods

The syntax for creating a Generic Method is as follows:

index.cs

index.cs

copy
123
returnType methodName<typeParameter1, typeParameter2, ..>(datatype1 arg1, ..) { // code here }

You can have one or more type parameters in a generic method.

We can execute generic methods as follows:

index.cs

index.cs

copy
1
methodName<typeParameter1, ..>(arg1, ..);

Following is a summary of how we can convert a simple Swap method to a generic method, which can support any data type:

We don't necessarily need to use the type parameters (like T) for defining the arguments. In fact there can be generic methods with no arguments at all:

index.cs

index.cs

copy
123
void ExampleMethod<A, B, C> () { // Code here }

It is not possible to directly use any kind of operators on arguments or variables defined using generic types:

index.cs

index.cs

copy
123
void ExampleMethod<A, B> () { return A + B; // Error }
